Restricting email notifications to an approved domain
To prevent organization information from leaking into personal accounts, organization owners can restrict email notifications about organization activity to a verified domain.
Restricting email notifications to domain email is available with GitHub Enterprise Cloud. For more information, see "GitHub's products."
When restricted email notifications are enabled in an organization, members can only receive email notifications about organization activity at an email address associated with the organization's verified domain. For more information, see "Verifying your organization's domain."
Outside collaborators are not subject to restrictions on email notifications for verified domains. For more information on outside collaborators, see "Permission levels for an organization."
